COM Port tab in Configuration option
Delete
Delete the existed connecting controller (one application needs to
connect at least one controller). Add/
Delete/
Modify Modify Modify the connecting controller or change the controller name.
COM Port Set the COM port that communicates with HMI
PLC
Station
Set PLC station number. If PLC does not set station number, it will
use this default setting. The range is between 0 ~ 255.
Password
Passwords are necessary for some connecting controllers before
communication.
Comm.
Delay
Time
Set delay time for waiting the startup of external controller
(i.e. PLC). The range is between 0 ~ 255 ms.
Timeout
Set communication time out time when communicating with the
external controller. The range is between 10 ~ 65535ms. .
Retry
Count
HMI will try to send a communication command to the external
controller repeatedly if the external controller does not respond
during communication. This option is used to set the number of
retry count times. A communication error dialog box will not appear
unless the number of retry count times is reached. The range is
between 0 ~ 255 times.
Controller
Settings
Optimize
When Optimize box is checked, optimization function is enabled. If
optimization function is enabled, all read addresses of all related
elements will be optimized.
When Communication Interrupt times then ignore box is checked, HMI stops
communicating with the PLCs after the communication interrupt time is reached. The
purpose of this function is to avoid the communication error dialog box will always show
on the HMI screen when the communication error occurs after HMI has retried. The range is
between 1 ~ 255 times.
If the user wants to recover the communication between HMI and PLCs again when HMI
stop communicating with the PLCs after the communication interrupt times are reached,
the user can use Bit 0 of the control block D1 (suppose that the stating address is D0) to
control HMI communication. When Bit 1 is set to ON, it will disable HMI communication.
When Bit 1 is set to OFF, it will enable HMI communication.
HMI
Station
Set HMI station number. The range is between 0 ~ 255.
Interface
Set communication interface. There are three options RS232, RS422
and RS485.
Data Bits There are two options 7 Bits and 8 Bits.
Comm.
Parameter
Stop Bits There are two options 1 Bits and 2 Bits.
